SPRING-SEAT.

SPECIFICATION forming part of Letters Patent N0. 765,946, dated July 26,1904.

Application filed May 18, 1904. Serial No. 208,547. (No model.)

To alZ whom, it may concern:

Be it known that 1, J OSEPH J. WIsDA, a citizen of the United States,residing at Defiance, in the county of Defiance and State of Ohio, haveinvented new and useful Improvements in Spring-Seats, of which thefollowing is a specification.

My invention pertains to spring-seats, more particularly spring-seatsfor vehicles; and it has for its object to provide a spring-seatcalculated to comfortably support a person irrespective of the roughnessof the road over which a vehicle is passing and one which is strong anddurable and is therefore well adapted to withstand the rough usage towhich such devices are ordinarily subjected.

The invention will be fully understood from the following descriptionand claims when taken in connection with the accompanying drawings,forming part of this specification, in which Figure 1 isaperspectiveview of the springseat constituting the present and preferred embodimentof my invention. Fig. 2 is a vertical central section of the same. Fig.3 is an enlarged detail inverted plan view illustrating the manner inwhich the verticallymovable frame of my novel seat is connected to theseat proper, and Fig. 4 is a View illustrative of the action of thesprings when the seat proper is depressed by the weight of a person.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which' A is the base of my novel seat. which maybe of any construction compatible withhthe purposes of my invention,although I prefer to make it in the form of a spider-frame and toprovide it with bolt-holes a, so as to adapt it for ready connection tothe frame of a cultivator or any other agricultural machine.

B B are upright guide-rods fixed to and ris-' ing from the base A at thefour corners thereof.

C is a guard-rail disposed at the back and sides of the seat and securedby nuts I) or other suitable means on the upper ends of the rods B.

D is a vertically-movable frame, preferably in the form of a spider,which has apertures loosely receiving the rods B, and is adapted to movevertically on said rods, and E is a seat proper, preferably ofsheet-metal, arranged on and fixedly connected to the frame D. I preferin connecting the seat proper, E, to the frameD to provide the seatproper with lugs c, which lugs are disposed at the under side of theseat proper and at opposite sides of a central portion (Z of the frameD, Fig. 3, and to pass a bolt 0 through the seat proper and said centralportion (Z of frame D, as best shown in Fig. 2.

F F are coiled springs which surround the guide-rods B and areinterposed between the base A and the guard-rail C. At an intermediatepoint in their height, and preferably between their middles and upperends, the said springs F receive between certain of their whirls thearms of the frame D, as best shown in Figs. 2 and 4. In virtue of thisconstruction it will be observed that when the weight of a person isimposed on the seat proper, E, and said seat proper and its frame D aredepressed the portions of the springs F below the seat proper will becompressed and the portions of the springs above said seat proper willbe expanded, while when the seat proper is relieved of weight theportions of the springs below the seat proper will expand and theportions of the springs above the seat proper Will contract. From thisit follows that when the seat proper is depressed it will be cushionedby the compression of the lower portions of the springs and theexpansion of the upper portions of the springs, and when the seat isrelieved of weight it will be returned to the position shown in Figs..1and 2 by the expansion of the lower portions and the compression of theupper portions of the springs and will be cushioned by said upperportions of the springs, and hence prevented, incident to its suddenupward movement, from injuring any of the parts of the construction. Italso follows that the several springs F are adapted to operateindependent of each other, and hence one spring will serve to cushionone corner of the seat proper or two springs to cushion one side of theseat proper without the other springs being afiected.

It will be appreciated from the foregoing that my novel spring-seat isadapted to take up all shock and jar incident to the passage of avehicle over a rough road or field and is therefore calculated tocomfortably support the driver of the vehicle. It will also beappreciated that the spring-seat is adapted to withstand rough usage andweather and that it embodies no delicate parts, such as are likely toget out of order after a short period of use.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to such specific construction andrelative arrangement of parts, as such changes or modifications may bemade in practice as fairly fall within the scope of my invention asclaimed.

Having described my invention, what I claim, and desire to secure byLetters Patent, 18-

l. The combination of a plurality of upright guides, a seat arranged tomove vertically between the guides, and coiled springs held by theguides and arranged below and above the seat and in engagement with thesame; the springs below the seat being also arranged to be compressedand the springs above the seat being also arranged to be expanded by thedepression of the seat.

2. The combination of a plurality of upright guides, coiled springs heldby the guides, and a seat arranged to move vertically between the guidesand having portions disposed between and in engagement with intermediatewhirls of the springs, whereby when the seat is depressed, the lowerportions of the springs will be compressed and the upper portionsthereof expanded.

3. The combination of a base, upright guiderods fixed to and rising fromthe base, aguardrail fixed on the upper portions of the said guide-rods,coiled springs surrounding the guide-rods and interposed between thebase and the guard-rail, and a seat arranged to move vertically betweenthe guiderods, and having portions receiving said rods and interposedbetween and arranged in engagement with intermediate whirls of thesprings.

4. The combination of a base, upright guiderods fixed to and rising fromthe base, coiled springs surrounding the guide-rods andinterposedbetween the base and a guard-raillixed on the upper portions of theguide-rods, the said guard-rail, a frame movable vertically and having acentral portion (Z, and also having apertured portions loosely receivingthe guide-rods and interposed between and arranged in engagement withintermediate whirls of the springs, a seat proper arranged on thevertically-movable frame, and having lugs disposed at opposite sides ofthe portion (Z of said frame, and a bolt connecting said seat proper andvertically-movable frame.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
